Yes. BT is a biological control, and not a pesticide. I use it on cabbage and tomatoes.
Organic farmers do use pesticides, they just use the ones approved for organic production, such as Bt insecticides.
By growing organic products.
A farmer must use seeds that are organic, unless there are none available, but regardless, the seeds must not be GMO seeds. No synthetic fertilizers or pesticides can be used, except in extreme conditions as determined by the USDA.
A farmer can claim his foods are organic, but in order to substantiate the claim, the farmer should back up that claim in some way, either by being certified by a reliable independent certification agency or seeking organic certification from the USDA.
HEB does carry organic. Sprouts in Austin is the closest Organic Farmer's Market.

Although organic farmers do in fact typically use some pesticides, they are greatly limited in what kinds of pesticides they are allowed to use. They therefore have to typically use lots of hand labor in the production of their crops. This is one reason why organic produce, for example, tends to be a little more costly than its counterpart.
One reason is that to grow crops the arable farmer meeds organic manure - this the dairy farmer has in plenty - the arable farmer could then supply the dairy farmer with organic feed to supplement the dairy farmers need for winter feed.
What sells best at a Farmer's Market are organic fruits and vegetables and organic meats. Most of the time I also see pastries, or homemade goods such as honey.
Say a farmer wants to count the number of organic tomatoes he harvested. He would he natural numbers. Not because the tomatoes were organic, but because natural numbers are counting numbers.
Bacillus thuringiensis is 'B.t.', which is an organic control of bagworms, caterpillars, hornworms and loopers.
